Solar PWM controller BL915C 12-24V/30A+USB for different batteries

Product detailed description

The BL915C PWM controller enables charging of 12-24V lead or lithium batteries with current up to 30A and connection of PV panels with output voltage max. 18V (for system voltage 12V) or 36V (for system voltage 24V) up to 360W(. and display of operating parameters.


Product parameters:

- pWM solar controllers connect the solar panels directly to the battery to be charged and after reaching the set or given battery terminal voltage, the subsequent regulation is solved by pulse current limitation-interruption. This happens at a frequency of units up to tens of Hz and is indicated by the flashing of an LED marked "charge" or "solar" in some controllers. Regulators are suitable for panels with a system voltage identical to the battery voltage, otherwise losses occur when part of the power is wasted due to inappropriate V-A characteristics of the panel.
